Prepare dressing
In a large bowl, whisk together all of the Dressing ingredients. Set aside.

Rinse and cook quinoa
Wash quinoa in 3 changes of cold water in a bowl, draining in a sieve each time.

In a three- to four-quart (3- to 4-quart) saucepan of boiling salted water (1 Tbsp salt for 2-quarts water), cook quinoa, uncovered, until almost tender, about ten (10) minutes.

Drain and steam quinoa
Drain in sieve. Then, set sieve in same pot with one-inch of simmering water, making sure that water does not touch the bottom of sieve. Cover quinoa with a clean folded kitchen towel with a lid on top of the sieve with a lid. The lid need not fit tightly.

Steam quinoa over Medium heat until tender, fluffy, and dry, about ten (10) minutes. Take pot off heat and remove lid. Let stand, still covered with towel, five (5) minutes.

Toss and serve
Add quinoa to dressing and toss until dressing is absorbed. Then, stir in remaining ingredients, seasoning with salt and pepper to taste.
